Marine Fuel Lines and Hoses

The marine fuel lines and hoses in any boat’s fuel system are key to ensure the safe operation and performance of the craft. Fuel assembly components must be machined to the highest quality and be attached securely to prevent potentially dangerous fuel line leaks. Wholesale Marine carries the top names in marine fuel lines and hoses including Attwood, T-H Marine, Moeller Marine, Sierra Marine Products,Whitecap Industries, and Flow Pro. Wholesale Marine believes that a little knowledge about a couple of fuel hose-related issues will assist boaters to better understand their fuel hoses and when these or their components may need replacement.

Directional Flow Issues

At the start of each season, check to make sure that where the fuel hose connects to the tank that the arrow aligns with the direction the fuel must flow. Installing or reinstalling a hose backwards is a common error. This is often overlooked or a clogged hose is mistakenly blamed. Just look for the flow direction arrow whenever installing a fuel tank hose.

Hose Check Valve Malfunction

When there is plenty of fuel in the tank, but no hose pressure, troubleshoot the check valve:

1) Remove the engine’s fuel hose connector and insert the end of a paper clip into the end with the steel ball.

3) Check for suction at the tank end using a finger. If there is no suction, the check valve is faulty and requires replacement.
